Sleep deprivation is a ubiquitous problem in society today. Robert Havekes, a neuroscientist at the University of Groningen in the Netherlands, says that everybody knows things go wrong in the brain with sleep deprivation, but he wanted to investigate whether it’s possible to assist the brain in memory recall.
